With reference to fig. 2 and fig. 1, the demolding operation principle of the automatic large rubber ring demolding device in this embodiment is as follows:
adjusting before demolding: the central ejector plate 6 is driven by the ejector oil cylinders 7 to move downwards to the lower limit position, and each wedge block driving oil cylinder drives each press-fitting wedge block 8 to slide in the radial direction so as to be completely retracted to the upper surface of the central ejector plate 6. The left and right pressing plates 2c and 3c are adjusted to appropriate positions according to the thickness of the mold outer ring 200, and a spacer (not shown) for supporting the mold outer ring 200 is placed at an appropriate position outside the center ejector mechanism, and the thickness of the spacer is thicker than that of the rubber ring 300.
Installing a rubber ring assembly part: placing a rubber ring assembly (shown in fig. 1) to be demolded on the central ejector plate 6 and ensuring that the mold inner core 100 is concentric with the central ejector plate 6, and then controlling the left outer ring pressing mechanism 2 and the right outer ring pressing mechanism 3 to synchronously move towards the central ejector mechanism until the left pressing plate 2c and the right pressing plate 3c are pressed downwards on the upper end surface of the mold outer ring 200.
And (3) demolding: the ejection cylinder 7 drives the central ejection plate 6 to move upward to an upper limit position, and in the process, the central ejection plate 6 is ejected upward into the rubber ring 300 to eject the mold core 100 out of the rubber ring 300, and the mold core 100 is removed. Next, each of the wedge driving cylinders drives each of the press-fitting wedges 8 to slide radially inward and outward until each of the press-fitting wedges 8 presses against the upper end surface of the rubber ring 300. At this time, the ejection cylinder 7 drives the central ejection plate 6 to move downward so as to drive each press-fitting wedge 8 to extrude the rubber ring 300 downward, and under the pushing of each press-fitting wedge 8, the rubber ring 300 and the outer ring 200 synchronously move downward until the outer ring 200 of the mold is supported on the cushion block. The ejection oil cylinder 7 continues to drive the central ejection plate 6 to move downwards, and the rubber ring 300 continues to move downwards relative to the outer ring 200 of the mold until the rubber ring falls on the base 1, so that the demolding of the rubber ring 200 is completed.
In some preferred embodiments, in order to prevent the press-fitting wedge 8 from crushing the upper end surface of the rubber ring 300 during the demolding, an annular iron ring is previously covered on the upper end surface of the rubber ring 300 to protect the rubber ring 300 before demolding.

It can be seen that in these preferred embodiments, the support and positioning of the outer ring 200 of the mold can be accomplished without the need for additional spacer blocks. In the demolding implementation process, when the separation of the mold outer ring 200 and the rubber ring 300 is realized, the outer ring upper ejection oil cylinder can push the outer ring upper ejection module 9 to upwards extrude the mold outer ring 200, so that the central ejection plate 6 can more easily realize the demolding of the mold outer ring 200.
In some preferred embodiments, in order to facilitate the clamping of the mold outer ring 200 by the left outer ring pressing mechanism 2 and the right outer ring pressing mechanism 3 and the support of the mold outer ring 200 by the outer ring top module 10, a plurality of outwardly protruding pressing lugs may be prefabricated at the periphery of the outer ring 200.
